Problems solved by technology

[0005] A disadvantage of known driver assistance systems is that the autonomous braking is interrupted when the vehicle in front is no longer detected by the vehicle in front
It has been shown that such driver assistance systems often end autonomous braking prematurely, thereby increasing the risk of a collision and the potential intensity of an accident

Embodiment Construction

[0031] figure 1 A motor vehicle 10 is shown, which has a front side 12 on which a front vehicle detection device 14 is arranged. The preceding vehicle detection device 14 is designed for detecting a preceding vehicle 16 and has a first component in the form of a camera 18 with field of view G and a second component in the form of a distance sensor 20 . Distance sensor 20 is designed to measure distance A from front 12 of motor vehicle 10 to the rear of vehicle 16 in front.

[0032]Furthermore, motor vehicle 10 has a driving speed detection device 22 in the form of a speedometer, a yaw rate sensor 24 and a deceleration sensor 26 . The preceding vehicle-detection device 14 , the travel speed detection device 22 , the yaw rate sensor 24 , and the deceleration sensor 26 are travel data-sensors that detect travel data of the automobile 10 . These devices are all connected to the electrical control unit 28 by means of cables. The electronic control unit 28 includes a digital mem...

Abstract

A driver assistance system includes a speed detector, a preceding vehicle detector having at least one video camera and at least one distance sensor for detecting the distance from a preceding vehicle, a device for determining the speed of the preceding vehicle, and an electronic control unit equipped to trigger an autonomous deceleration of the vehicle with the presence of predetermined brake trigger driving data and to terminate the autonomous deceleration with the presence of predetermined brake abortion driving data. The control unit effects: redundant detection of preceding vehicle driving data, and non-redundant detection of preceding vehicle driving data if a redundant detection is not possible. The non-redundantly detected preceding vehicle driving data is compared to preceding vehicle driving data redundantly detected within a predetermined time, and the non-redundantly detected data is used to control the autonomous deceleration if it corresponds to the redundantly detected data.

Description

[0001] Instructions for Divisional Application [0002] This application is a divisional application of the Chinese invention patent application whose application number is 200980118429.8, the application date is February 24, 2009, and the invention name is "driver assistance system". technical field [0003] The invention relates to a driver assistance system for a motor vehicle, comprising: (a) a driving speed detection device for detecting driving data in the form of the driving speed of the motor vehicle; (b) a preceding vehicle detection device having at least A camera as the first part, and having at least one distance sensor as the second part, is used to detect the travel data in the form of the distance from the preceding vehicle traveling in front of the automobile; (c) the preceding vehicle speed-acquiring device, For knowing the speed of the preceding vehicle; and (d) an electric control unit configured to trigger autonomous braking of the vehicle when there is pr...
